"Sweeneyâ  s was a lifesaver. We bought a house with a pool that needed a complete overhaul. After many interviews with others, we thankfully discovered Kenneth Sweeney. Carefully recovered, replaced the lining, drains, filter, electrical, provided gas pump, and worked with gas company to ensure all was safe. We needed a new cover, they also serviced the pool weekly. This is a serious investment and so vital to hire a safe company with quality and professional staff that care. Sweeneyâ  s team is the best. Finally the nightmare we started out with turned out to be an oasis in our backyard. My granddaughter learned how to swim this summer and we hosted her 4th birthday celebration with a lifeguard in our backyard. Thank you Kenny and team for making our backyard a vacation spot for us and our family. We are truly grateful for you."

"This company maintained our pool all summer long. The pool we have is a large gunite pool with salt water, it is hard to maintain and keep clear but they did it. If there was ever an issue or concern, Clinton responded himself within a few hours of contacting them. When our pool filter shorted out in a storm, they were there within 2 days with a new filter and gave us a fair price. The billing is easy, they give you a paper copy as well as send an email providing a bunch of payment options. The receptionist is efficient and someone always responds and answers. They send reminder emails before coming to service your pool. Communication and work is great."

"The owner showed up on the planned afternoon appointment day and called 20 minutes before arrival. He quickly assessed the problem with my air conditioner. Despite spending over two hours working in my attic, the price he charged was very reasonable and lower than what I anticipated. If I have any future air conditioner problems I will definitely call this owner/company."

"Palatial Pools installed a large in-ground pool and spa for me back in 2007. I did not want to see or hear the equipment, so they installed that about one hundred feet away in a "hidden" location. Douglas Vunk was my main contact for this project and he and his crew did a great job with everything. Since initial installation, I have used Palatial Pools as my regular cleaning and maintenance company. Douglas is always on time for scheduled services. He also has provided me with a prompt emergency service once, and is flexile with his scheduling when the scheduled service date does not work for me. Douglas is a very knowledgeable and technical Professional, but has the ability to explain everything in terms that I can understand. I have recommended Palatial to friends and colleagues, and will continue to use Palatial and Douglas Vonk as my Pool Technician."

"I have been using Big Blue Pool for over nine years now. Let me start off by saying Emma is one of the Frontline workers for Big Blue Pool, She is professional she is cheerful and a pleasure to talk to , She is so full of energy I just love to talk to her each year. Mike the owner of Big Blue is great he’s professional he is a great person to deal with very fair and stands behind everything Big Blue does, they always seem to amaze me by what they’ll do for their customers. They open and close my pool every year, come immediately whenever I need a service call. They have done many service calls on my pool, and have given me advice on how to do a lot of things myself which isn’t common for a business when you think about it. There workers have always done a good job and were always very pleasant and willing to answer questions.. It also seems that everyone they recommend for certain things they don’t do , (for example Bob the diver fixes leaks for them) Has the same Work ethics they do. If you need a pool company for anything this is the company that you want to use. If I could I would’ve given them 10 stars."

FAQs for swimming pool heaters repair or service projects in Cold Spring Harbor, NY

Replacing a pool heater costs $3,000 on average. Final pricing depends on the type of heater (gas, electric, or solar) and your pool's size. Factor for swimming pool repair costs, at an average of $3,800. When you start experiencing issues with your pool heater, other equipment and structural failures often follow. Installation is often the least expensive for electric and gas heaters. Heat pumps and solar panels often cost several thousand dollars more to install.

A pool heater’s lifespan is determined by its type and proper upkeep. Solar heaters last 20 to 25 years, electric heat pumps perform for five to 10 years, and gas heaters remain effective for 5 years. Regular pool maintenance safeguards performance and prevents premature failure. Ensuring that you adhere to a strict annual service schedule protects your investment and maintains consistent heating efficiency.

Depending on the size of your pool, location, climate, and current energy prices, you’ll spend up to $20 per hour to heat a pool using propane, $9 per hour using natural gas, and $1 to $2 per hour for a heat pump. Northern climates require more energy and can double the price. Standard estimates allow homeowners to easily estimate the cost of heating a pool for a month. Propane heaters, for example, are known to burn around 1 gallon per hour per 100,000 BTUs.

An electric or gas heat pump will take eight to 14 hours to heat a pool, while a solar heat pump takes 24 to 72 hours. Multiply the number of gallons by 8.34 to get your total pounds of water. Divide this figure by your heater's BTU rating to determine how many hours it takes to raise the water temperature by 1 degree Fahrenheit.

If your pool heater is not raising the water temperature to the desired level, the issue is caused by cold ambient conditions rather than a malfunction. The best solution is to install a solar cover that locks in heat and boosts efficiency. A solar cover costing $120 to $250 enhances heat retention, ensuring your heater performs at its peak. Additionally, verify that all settings—such as thermostat calibration and water circulation—are properly adjusted to support optimal heating.

Regular annual maintenance is crucial to keep your pool heater running efficiently and to avoid high repair costs. Investing $100 to $200 in yearly maintenance prevents issues such as excessive noise, surging energy bills, and malfunctioning controls. This proactive care not only prolongs your heater’s lifespan but also ensures reliable performance throughout the season. Always refer to your warranty guidelines to follow the required maintenance procedures.
